Technologies for presenting public and private images

ABSTRACT

Technologies for displaying public and private images includes a display device and one or more user viewing devices. The display device is configured to display or generate a personalized image or video that is viewable by an authorized user viewing device and not viewable by unauthorized viewing devices. To facilitate the display of the personalized images, the display device and the user viewing device(s) may negotiate a display protocol to be used by the display device to display the personalized image in a private manner. In some embodiment, the display device may also display a public image or video that is viewable by unauthorized viewing devices and/or individuals without viewing devices.

BACKGROUND

Display devices are used to display information and entertainment content to viewers in the vicinity of the display. Display devices may be public or private. Public displays, such as crowd displays at sporting events, advertisement displays, and other displays in public areas typically display images and information for consumption by the general public. Private displays, such as computer displays, personal televisions, personal mobile device displays, and other displays controlled by a private entity are generally used to display personal images or information intended for consumption by the user of such devices or a select group of authorized individuals.

Display devices, both public and private, are becoming ubiquitous in the everyday life of many people. Additionally, as display technology improves, displays are increasingly being integrated and/or embedded in other devices or articles. For example, display technology is currently being incorporated into transparent windows, clothing, personal accessory items, and other devices. Such proliferation of display devices creates difficulties in communicating targeted information to individuals while maintaining a degree of privacy over such information.

Referring now to FIG. 1, a system 100 for displaying personalized image(s) to a viewer includes a personalization public display device 102 and one or more user viewing devices 104, which may be worn or otherwise operated by a corresponding user 112. In use, as discussed in more detail below, the display device 102 is configured to display a personalized image or images (e.g., video) to a user, or group of users, of a particular user viewing device 104 (e.g., smart glasses, a smart phone, or other viewing device) in a private manner. In particular, the display device 102 displays or presents the personalized image(s) such that the personalized image(s) are viewable via use of an authorized user viewing device(s) 104 and not viewable by other unauthorized user viewing devices 104 and/or users without a user viewing devices 104. To do so, the display device 102 and the targeted user viewing device 104 communicate with each other to establish one or more display protocols, which are used by the personalization public display device 102 to display or otherwise present the personalized image(s) in the private manner. The personalized images may be displayed by the display device 102 itself (e.g., in an encrypted or obscured format) or provided to the authorized user viewing device 104 by the display device 102 or an associated cloud service. For example, in some embodiments, the display device 102 may display the personalized image on a local display using any suitable display protocol capable of obscuring or encrypting the personalized image on the local display such as, for example, a polarization display protocol, a color filtering display protocol, a view segmentation display protocol, a layered depth variation display protocol, a pixel obfuscation display protocol, a pixel encoding display protocol, or other display protocol that allows the display device 102 to display the personalized image in an obscured or encrypted manner, while also allowing the targeted user viewing device 104 to properly view the personalized image. Alternatively, in other embodiments, the display device 102 (or an associated cloud service) may transmit the personalized image(s) to the authorized user viewing device 104 for display or presentation on a local display, projection surface, or lens of the user viewing device 104. In such embodiments, the personalized images may be embodied as still image(s) or streamed images/video/audio (e.g., a video according to a Moving Picture Experts Group (MPEG) standard). In some embodiments, the display device 102 overlay the personalized images/video over a viewable area of the display or projection surface to provide an augmented reality view as discussed in more detail below.

To view the personalized image, the user viewing device 104 also utilizes the established display protocol by, for example, decrypting a received or viewable encrypted personalized image, operating a local display according to the display protocol, controlling visual characteristics of a viewer lens, or other viewing technique based on the established display protocol. In some embodiments, the display protocol used to display and view the personalized image may be modified over time based on, for example, the user's location relative to the display device 102, security timeouts, bandwidth or throughput considerations, and/or other criteria.

An example of the operation of the system 100 is depicted in FIG. 1. A user 110 is shown viewing a display of the personalization public display device 102. However, because the user 110 does not have a user viewing device 104, the user 110 sees a public image 120 that is displayed on the display by the display device 102. The public image 120 (e.g., a cartoon character) is viewable by the general public, e.g., by anyone viewing the display device 102 without an authorized user viewing device 104. Conversely, a user 112 a is viewing the display of the display device 102 with an authorized user viewing device 104 that has established a display protocol with the display device 102. As such, the user 112 a sees a personalized image 130, such as a targeted advertisement for a shirt. Depending on the display protocol used, the user 112 a may view the personalized image by looking at a local display of the user's 112 a viewing device 104 or by looking at the display of the display device 102. Similarly, another user 112 b is viewing the display of the display device 102 with a different authorized user viewing device 104 that has established a different display protocol with the display device 102. As such, the user 112 b sees a different personalized image 132, such as a targeted advertisement for a new computer. Again, the user 112 b may view the personalized image by looking at a local display of the user's 112 b viewing device 104 or by looking at the display of the display device 102 depending on the particular display protocol used. In this way, the display protocols used by the personalization public display device 102 and the authorized user viewing device(s) 104 may be used to establish a private viewing modality between the two devices 102, 104. Of course, a group of users may be authorized to view the same personalized image by implementing the same display protocol in some embodiments.

Referring now to FIG. 2, the personalization public display device 102 may be embodied as any type of display device capable of displaying, streaming, or otherwise presenting images, video and/or audio to a viewer and performing the functions described herein. For example, the display device 102 may be embodied as a crowd display, an advertisement display, an information display, a television, a smart appliance, a computer device, or other device or display surface having display capabilities.

The display 208 may be embodied a display local to the display device 102 or remote therefrom, but communicatively to thereto. For example, in some embodiments, the display 208 may be located at one location, while the remaining components of the display device 102 are located at another location remote from the display 208 but communicatively coupled thereto (e.g., via an interconnection, network, etc.) Although shown in FIG. 1 as a single display, it should be appreciated that the display 208 may embodied as multiple, individual displays in other embodiments. For example, the display 208 may be embodied as an arrangement of displays located in, for example, a shopping mall or similar retail location. Alternatively, the display 208 may be embodied as a single display in some implementations. The individual display(s) 208 may be embodied as any type of display capable of displaying digital information such as a liquid crystal display (LCD), a light emitting diode (LED), a plasma display, a cathode ray tube (CRT), or other type of display device. Additionally, the display(s) 128 may be of any size or shape and have any suitable resolution, color, and/or have any other feature or quality commonly found in a display. In some embodiments, the display 208 may be attached to, embedded in, or otherwise incorporated into other devices or structures in some embodiments. For example, the display 208 may be incorporated in a transparent window, in clothing, in a smart device, or other device or article in which the display 128 is generally viewable by a public population.

The data storage 210 may be embodied as any type of device or devices configured for short-term or long-term storage of data such as, for example, memory devices and circuits, memory cards, hard disk drives, solid-state drives, or other data storage devices. In some embodiments, the display device 102 may also store the personalized images displayed on the display 208 and/or transmitted to the user viewing device 104. Additionally, the display device 102 may store the various display protocols and viewer policies in the data storage 210 which are used to select and display the personalized images as discussed in more detail below.

In some embodiments, the display device 102 may also include one or more viewer detection sensors 212. The viewer detection sensors 212 may be embodied as any type of sensor and/or circuit capable of sensing, detecting, or otherwise generating sensor data indicative of the presence of a user viewing device 104 within the proximity or vicinity of the display device 102. For example, the viewer detection sensor 212 may be embodied as a communication circuit (e.g., the communication circuit 206 or portion thereof) configured to sense or detect communications from a user viewing device 104, proximity sensors and associated circuitry configured to detect the presence of a user viewing device 104, camera or image sensors and associated circuitry to detect the presence of a user viewing device 104 based on capture images, or other sensor or sensor circuitry capable of detecting the presence of a user viewing device 104 in proximity to the display device. As discussed in more detail below, upon detecting the presence of a user viewing device 104 within the vicinity, the display device 102 may initiate a negotiating procedure to establish the display protocols used to display the personalized image to a user of the authorized user viewing device 104.

In some embodiments, the display device 102 may further include one or more peripheral devices. Such peripheral devices may include any type of peripheral device commonly found in a display device or other computer device such as, for example, a hardware keyboard, input/output devices, peripheral communication devices, and/or other peripheral devices.

Referring now to FIG. 3, the user viewing device 104 may be embodied as any type of device capable of viewing a personalized image displayed or transmitted by the personalization public display device 102 (or an associated cloud service). For example, the user viewing device 104 may be embodied as a pair of smart glasses, electronic corneal implants, a smart phone or tablet, or other viewing device. Depending on the type of display device 102 and/or implementation of the system 100, the user viewing device 104 may be configured to view the personalized images by providing real-world augmentation, visual filtering, and/or displaying of the personalized images locally. For example, the user viewing device 104 may be embodied as a pair of smart glasses configured to project or overlay an image of the personalized images onto a viewing lens of the glasses or configured to control a visual filter or shutter embedded in the viewing lens of the glasses. As an alternative example, the user viewing device 104 may be embodied as smart phone, camera, or other device having a local display onto which the personalized image may be displayed (e.g., overlaid onto a real-time image of the real-world to provide an augmented reality). As such, the user viewing device 104 may be embodied as any type of device usable by a user to view the personalized images.

In the illustrative embodiment, the user viewing device 104 includes a processor 300, an input/output subsystem 302, a memory 304, a display 308, a communication circuit 306, and a data storage 310.

For example, the display 308 may be embodied as a liquid crystal display (LCD), a light emitting diode (LED), a plasma display, a cathode ray tube (CRT), or other type of display device. Additionally or alternatively, the display 308 may be embodied as, or otherwise include, a viewing lens 320 (e.g., the transparent viewing glass of a pair of smart glasses, a retinal implant, etc.). In such embodiments, the user viewing device 104 may be configured to project the personalized image onto the viewing lens 320 in an augmented reality manner as discussed above. Alternatively, in some embodiments, the user viewing device 104 may be configured to control the viewing lens 320 to adjust visual filtering, shuttering, or other visual quality or characteristic of the viewing lens 320. For example, the viewing lens 320 may include an adjustment mechanism (e.g., shutter, iris, segmented view adjustment, etc.) operable to control a visual characteristic of the viewing lens. In such embodiments, the display protocol may be embodied as a control protocol for the adjustment mechanism.

The data storage 310 may be embodied as any type of device or devices configured for short-term or long-term storage of data such as, for example, memory devices and circuits, memory cards, hard disk drives, solid-state drives, or other data storage devices. In some embodiments, the user viewing device 104 may store a local viewer policy in the data storage 310, which is transmitted to the display device 102 to facilitate the selection of a personalized image.

In some embodiments, the user viewing device 104 may also include one or more display detection sensors 312. Similar to the viewer detection sensor(s) 212, the display detection sensors 312 may be embodied as any type of sensor capable of sensing, detecting, or otherwise generating sensor data indicative of the presence of a personalization public display device 102 within the proximity or vicinity of the user viewing device 104. For example, the display detection sensor 312 may be embodied as a communication circuit (e.g., the communication circuit 306 or portion thereof) configured to sense or detect communications from the display device, respond to such communications, and/or transmit an announcement of the presence of the user viewing device 104.

For example, the user viewing device 104 may infer the presence of a display device 102 based on the user's interactions with the display 308 and/or other components of the user viewing device 104.

The user viewing device 104 may also further include one or more peripheral devices in some embodiments. Such peripheral devices may include any type of peripheral device commonly found in a viewing device or other computer device such as, for example, a hardware keyboard, input/output devices, peripheral communication devices, and/or other peripheral devices.

Referring back to FIG. 1, in some embodiments, the system 100 may also include a remote display server 106, which is accessible by the display device 102 over a network 108. In such embodiments, the personalization public display device 102 may be embodied as a “low featured” display operated by the remote display server 106 over the network 108. For example, the personalized images may be stored on the remote display server 106, and the server 106 may select which personalized images to display as discussed in more detail below. In such embodiments, the network 108 may be embodied as any type of communication network capable of facilitating communication between the display device 102 and the remote display server 106. As such, the network 108 may include one or more networks, routers, switches, computers, and/or other intervening devices. For example, the network 108 may be embodied as or otherwise include one or more local or wide area networks, cellular networks, publicly available global networks (e.g., the Internet), an ad hoc network, a short-range communication network or link, or any combination thereof.

Referring now to FIG. 4, in use, the personalization public display device 102 establishes an environment 400. The illustrative environment 400 includes a viewer detection module 402, a display personalization module 404, and a display control module 406. The various modules of the environment 400 may be embodied as hardware, firmware, software, or a combination thereof. For example, the various modules, logic, and other components of the environment 400 may form a portion of, or otherwise be established by, the processor 200 or other hardware components of the display device 102.

The viewer detection module 402 is configured to detect the presence of a user viewing device 104 within proximity to the display device 102. To do so, the viewer detection module 402 may analyze the sensor data generated by the viewer detection sensors 212. For example, in some embodiments, the viewer detection module 402 may monitor a local network for communications from a user viewing device 104. Additionally or alternatively, the viewer detection module 402 may transmit or broadcast a discovery request to prompt a response from nearby user viewing device 104. Further, in some embodiments, the viewer detection module 402 may analyze image or other data generated by the viewer detection sensors 212 to determine the presence of a user viewing device 104. For example, the viewer detection module 402 may analyze images of the local vicinity to identify individuals in the images (e.g., via facial recognition, video analytics, etc.) and determine whether the individuals are carrying or using user viewing devices 104. The viewer detection module 402 may pair the identified individuals with the detected user viewing devices 104. As such, it should be appreciated that the viewer detection module 402 may utilize any suitable methodology and/or technology to detect and establish communication's with a user viewing device 104.

The display personalization module 404 is configured to negotiate with the target user viewing device 104 to establish the display protocol(s) to be used to display the personalized image. To do so, the display personalization module 404 utilize a viewer policy database 410, which may include data or policies dictating or identifying criteria on which the display protocol(s) may be selected. For example, the viewer policy database 410 may include data that identifies which display protocol(s) a particular user viewing device 104 is capable of implementing (e.g., whether the user viewing device 104 is capable of visual filtering). Additionally or alternatively, the viewer policy database 410 may include data indicative of a display protocol preference of a user of a particular user viewing device 104. The viewer policy database 410 may be updated over time based on, for example, historical interactions with the authorized user viewing device 104. Additionally or alternatively, the user viewing device 104 may provide or update the viewer policy to the display device 102 as discussed in more detail below.

The display personalization module 404 also manages the selection of images, videos, and/or other digital content (e.g., applications or other interactive experiences) to be displayed or otherwise presented by the display device 102. To do so, the display personalization module 404 includes an image selection module 408 configured to determine or select public and/or personalized image(s), video, and/or other media to be presented by the display device 102. For example, the image selection module 408 may select or determine one or more public images 420 to be displayed or presented by the display device 102. As discussed above, the public images 420 are viewable by the general public (e.g., individuals without a user viewing device 104 and/or unauthorized user viewing devices 104). Additionally, the image selection module 408 may select a personalized image 422 for display or presentation to a user of an authorized user viewing device 104 using the established display protocol.

Depending on the particular implementation, the image selection module 408 may utilize any suitable criteria or data to select the personalized image 422. For example, the image selection module 408 may select a personalized image 422 based on criteria related to the personalized image 422 itself and/or based on criteria related to a user of the targeted user viewing device 104. In one illustrative example, the image selection module 408 may select a personalized image 422 based on a current advertisement campaign, the time of day, local environment conditions, in response to detected or identified events, and/or other criteria that is not directly related to the user of the user viewing device 104. Additionally or alternatively, the image selection module 408 may select the personalized image 422 based on aspects or characteristics of the user of the user viewing device 104 such as, for example, physical characteristics of the user, past purchasing behavior, personal preferences, and/or the like. Such user preferences or characteristics may be included in the viewer policy database 410, which may be used by the image selection module 408 to select the personalized image 422. As discussed above, the user viewing device 104 may transmit or otherwise provide the viewer policies on which the personalized image selection is based to facilitate some control or filtering by the user over the selection process (e.g., the type of advertisements, brands, or content the user is interested in).

The personalized images 422 may be embodied as pre-generated images, video with or without associated audio, or other content, which are selected by the image selection module 408 based on a viewer policy or other data. Alternatively, in some embodiments, the personalized images 422 may be generated in real-time or near real-time based on the viewer policy or other data. Although shown in FIG. 4 as being stored on the personalization public display device 102, the public images 420 and the personalized images 422 may be stored on the remote display server 106 in some embodiments. As such, the display device 102 may retrieve the public images 420 and/or personalized images 422 as needed. In such embodiments, the environment 400 may include an image retrieval module 430 to retrieve the public images 420 and/or personalized images 422 from the remote display server 106.

The display control module 406 is configured to control the display(s) 208 to present the selected personalized image(s) 422, as well as any public image 420. As discussed in more detail below, the display control module 406 may display or otherwise present the selected personalized image 422 based on the established display protocol. For example, the display control module 406 may control the display 208 to display or present a personalized image in an encrypted or obscured manner, which may be subsequently decrypted or unobscured by the user viewing device 104. Depending on the established display protocol, the display control module 406 may be configured to control aspects of the display itself to display the personalized image 422 in an encrypted or obscured manner. For example, the display control module 406 may be configured to control a visual filter, shuttering, colorization, pixelization, of other aspect of the display 208 to display the personalized image 422.

Referring now to FIG. 5, in use, the user viewing device 104 establishes an environment 500. The illustrative environment 500 includes a display detection module 502, a viewer personalization module 504, and a viewer display module 506. The various modules of the environment 500 may be embodied as hardware, firmware, software, or a combination thereof. For example, the various modules, logic, and other components of the environment 500 may form a portion of, or otherwise be established by, the processor 300 or other hardware components of the user viewing device 104.

The display detection module 502 is configured to detect the presence of a display device 102 in the local vicinity. To do so, in some embodiments, the viewer detection module 402 may be configured to communicate with the display device 102 to announce the presence of the user viewing device 104. For example, the display detection module 502 may respond to discovery requests or similar communications received from the display device 102 and/or initiate communications with the display device 102 to indicate that the user viewing device 104 is nearby.

The viewer personalization module 504 is configured to negotiate with the display device 102 to establish the display protocol(s). Similar to the display personalization module 404, the viewer personalization module 504 may utilize a local viewer policy database 510 to establish the display protocols. The viewer policy database 510 may include, for example, polices or other data that indicate which display protocols the user viewing device 104 is capable of implementing. As such, the viewer personalization module 504 may transmit such data to the display device 102 during the display protocol negotiations.

The viewer policy database 510 may also include policies or other data useable to identify or select a personalized image 422 for presentation to a user of the user viewing device 104. For example, the viewer policy database 510 may include policies or data that identify personal preferences or characteristics of the user of the user viewing device 104 such as, for example, physical characteristics of the user, past purchasing behavior, likes, dislikes, and/or the like. Again, the viewer personalization module 502 may transmit such data to the display device 102 for use in selecting the personalized image(s) 422.

The viewer display module 506 is configured to control the local display 308 and/or viewing lens 320 to allow viewing of the personalized image(s) presented by the display device 102. Depending on the particular display protocol used, the viewer display module 506 may locally display the personalized image 422 or control the viewing lens 320 to allow viewing of the personalized image 422 displayed by the display device 102. For example, in some embodiments, the viewer display module 506 may be configured to decrypt or unobscured a personalized image 422 displayed, presented, or transmitted by the display device 102 and locally display or project the decrypted/unobscured personalized image 422 on the local display 308. In doing so, the viewer display module 506 may locally display the personalized image 422 in an augmented reality manner (e.g., overlaid on the display 208 of the display device 102). Additionally or alternatively, the viewer display module 506 may control aspects of the viewing lens 320 to allow viewing of the personalized image 422 on the display 208 of the display device 102. For example, the viewer display module 506 may control an adjustment mechanism of the viewing lens 320 to control visual filtering, shuttering, or other visual quality of the viewing lens 320 to facilitate the viewing of the personalized image 422.

Referring now to FIGS. 6 and 7, in use, the personalization public display device 102 may execute a method 600 for personalizing display of images to a viewer. The method 600 beings with block 602 in which the display device 102 monitors for user viewing devices 104, and/or users of user viewing devices 104, in proximity to the display device 102. As discussed above, the display device 102 may use any suitable technology or methodology to discover local user viewing devices 104. For example, in block 604, the display device 102 may monitor communication traffic of a local network (e.g., a local ad hoc network) for announcements or other communications from a new user viewing device 104. Additionally or alternatively, in block 606, the display device 102 may transmit discovery requests and monitor responses to such signals. For example, in some embodiments, the display device 102 may periodically broadcast a discovery request to detect new user viewing devices 104 within the vicinity. Further, in some embodiment, the display device 102 may receive queries from a user viewing device 104 in block 608. In such embodiments, the user viewing device 104 may be configured to periodically broadcast queries searching for local display devices 102 as discussed below.

In block 610, the display device 102 determines whether a new user viewing device 104 has been detected in local proximity to the display device 102. It should be appreciated that the range of detection (i.e., the proximity threshold) used by the display device 102 to determine the presence, or lack thereof, of a user viewing device 104 may vary depending on the implementation and/or the methodology used to detect the user viewing device 104. For example, in some embodiments, a user may pre-register with an advertisement service or other display service to receive the personalized images from a network of displays 102. In such embodiments, the location of the user relative to a nearby display 102 may be tracked based on the location of the user viewing device 104 or other mobile device (e.g., via global positioning system (GPS) tracking). Of course, other methods for determining the location of the user relative to a local display device 102 may be used in other embodiments.

If no user viewing device 104 is detected within the proximity threshold, the method 600 advances to block 612 in which the display device displays or presents a public image 420. As discussed above, the public image 420 may be embodied as a default image that is viewable by the general public. Alternatively, in some embodiments, the display device 102 may not display a public image 420 but rather obscure the display and/or any personalized images 422 displayed on the display in block 620, such that the personalized image(s) 422 is not viewable by an unauthorized user viewing device 104. Additionally or alternatively, the display device 102 may display or present a default personalized image in block 612. The default personalized image may be selected based on known or expected users or user viewing devices 104 known or expected to be within the vicinity (e.g., based on an instruction from an associated cloud display service or otherwise inferred to be near the display device 102, even though the user or user viewing device 104 was not successfully detected). Regardless, the method 600 subsequently loops back to block 602 in which the display device 102 continues to monitor for user viewing devices 104.

If, however, the display device 102 determines that a new user viewing device 104 is present, the method 600 advances to block 616. In block 616, the display device 102 authorizes the detected user viewing device 104 to view personalized images. To do so, the display device 102 may authorize the user viewing device 104 based on any suitable criteria. For example, in block 618, the display device 102 may receive identification data from the user viewing device 104. The identification data may be embodied as any type of data that provides an identification of the user viewing device 104 and/or the user 112 of the user viewing device 104. For example, the identification data may include a model number, serial number, globally unique identification (GUID) number, or other identity data associated with the user viewing device 104. Additionally or alternatively, the identification data may include data that identifies the user 112. In such embodiments, the identification data may form a portion of the viewer policy 410. Further, in some embodiments, the display device 102 may authorize the user viewing device 104 based on the display capabilities of the user viewing device 104. For example, the display device 102 may authorize the user viewing device 104 to view personalized images 422 based on which display protocols are useable by the user viewing device 104.

In block 620, the display device 102 determines whether the detected user viewing device 104 is authorized. If not, the method 600 advances to block 612 in which the display device 102 display the public image 420 (or default personalized image) as discussed above. The method 600 subsequently loops back to block 602 in which the display device 102 continues to monitor for user viewing devices 104.

If, however, the display device 102 determines that the detected user viewing device 104 is authorized to view a personalized image, the method 600 advances to block 622. In block 622, the display device 102 establishes one or more display protocols with the detected user viewing device 104. To do so, in some embodiments, the display device 102 may be configured to determine or select the display protocol based on the viewer policies stored in the database 410 and/or received from the user viewing device 104. In such embodiments, the display device 102 may transmit the selected display protocol(s) to the user viewing device 104 in block 624. Additionally or alternatively, the user viewing device 104 may select or request the display protocol and transmit the selected/requested display protocol, which is received by the display device in block 626. Of course, in some embodiments, the display device 102 and user viewing device 104 may participate in a more complex negotiation based on other criteria and using any suitable negotiation methodology to arrive at a suitable display protocol.

The method 600 subsequently advances to block 628 of FIG. 7 in which the display device 102 determines the personalized image(s) 422 to be displayed or presented to the authorized user viewing device 104. As discussed above, the display device 102 may utilize any suitable criteria or data to select the personalized image 422 for display or presentation. For example, in some embodiments, the display device 102 may select the personalized image 422 based on a viewer policy retrieved from the local viewer policy database 410 in block 630. Additionally or alternatively, the display device may select the personalized image 422 based on a viewer policy received from the user viewing device 104 in block 632. In some embodiments, the block 634, the display device 102 may infer a viewer policy on which to select the personalized image 422. For example, the display device 102 may select the personalized image 422 based on the current time of day, environmental conditions, current sales, advertisement restrictions or conditions, and/or other criteria or data.

After the display device 102 has determined or selected a personalized image(s) 422 for presentation to a user of the authorized user viewing device 104, the method 600 advances to block 636. In block 636, the display device 102 controls the display 208 to display or present the selected personalized image 422. A discussed above, the display device 102 displays or presents the personalized image 422 in a private manner using the negotiated display protocol such that the personalized image 422 is viewable by the authorized user viewing device 104 and not viewable by unauthorized user viewing devices 104 or other unauthorized viewers. For example, in block 638, the display device 102 may display an encrypted or obscured personalized image 422 using the negotiated display protocol. The encrypted/obscured personalized image 422 is not discernable or otherwise viewable by unauthorized user viewing devices 104. However, user viewing devices 104 employing the negotiated display protocol can decrypted (e.g., via corresponding decryption keys) or otherwise unobscured (e.g. via controlling operation of the viewing lens 320) the personalized image 422 to allow viewing of the personalized image 422 by the user(s) of the authorized user viewing device 104. In other embodiments, the display device 102 may transmit the personalized images(s) 422 directly to the user viewing device(s) 104 for presentation thereon. Further, in some embodiments, the display device 102 may be configured to update or periodically change the personalized image 422 displayed or presented to the authorized user viewing device 104. For example, the display device 102 may change the personalized image 422 in response to interaction from a user of the user viewing device 104 on the user viewing device 104 and/or on the display device 102 itself.

It should be appreciated that the display device 102 may utilize multiple, different display protocols contemporaneously with each other to provide different personalized images 422 to different authorized user viewing devices 104. In such embodiments, only those personalized images 422 displayed according to the determined display protocol would be viewable by the corresponding authorized user viewing device 104. That is, personalized images displayed or presented by the display device 102 using another display protocol would not be viewable by an authorized user viewing device 104 configured to use a different display protocol. In this way, the display device 102 may manage multiple personalized images 422 while maintaining privacy between the various personalized images 422.

In some embodiments, the method 600 may advance to block 640 after presentation of the personalized images 422. In block 640, the display device 102 determines whether to track the authorized user viewing device 104 (or user thereof). If not, the method 600 loops back to block 602 in which the display device 102 continues to monitor for additional user viewing devices 104. If, however, the display device 102 determines to track the authorized user viewing device 104, the method 600 advances to block 644.

In block 644, the display device 102 determines the location of the user viewing device 104 or user thereof. To do so, the display device 102 may utilize any suitable technology or methodology to track the user viewing device 104. For example, the display device 102 may track the user viewing device 104 using proximity sensors, global positioning system data, image devices, and/or other devices useful in monitoring the location of the user viewing device 104 relative to the display device 102. Subsequently, in block 646, the display device 102 controls the display 208 to display or present the personalized image 422 based on the relative location of the user viewing device 104. For example, in block 648, the display device 102 may modify or update the display protocol used to display or present the personalized image 422 based on the present location of the user viewing device 104 relative to the display device 102. In this way, the display device 102 may maintain a level of privacy of the personalized images 422 while the user of the authorized user viewing device 104 moves around. The modification of the display protocol may be particularly useful in those embodiments in which the display protocol adjusts the visual characteristics or properties of the display 208 itself, such as polarization, color filtering, and/or view segmentation.

Referring now to FIG. 8, in use, the user viewing devices 104 may execute a method 800 for viewing a personalized image. The method 800 begins with block 802 in which the user viewing device 104 monitors for display devices 102 in the local vicinity. Similar to the display device 102, the user viewing device 104 may use any suitable technology or methodology to discover a nearby display device 102. For example, in block 804, the user viewing device 104 may monitor communication traffic of a local network (e.g., a local ad hoc network) for announcements or other communications from a display device 102. Additionally or alternatively, in block 806, the user viewing device 104 may receive and respond to discovery request received from a local display device 102. Further, in some embodiments, the user viewing device 104 may periodically or responsively transmit queries to nearby display devices 102 in block 808.

In block 810, the user viewing device 104 determines whether a display device 102 has been detected nearby. If not, the method 800 loops back to block 802 in which the user viewing device 104 continues monitoring for a display device 102. If, however, a display device 102 has been detected in the local proximity, the method 800 advances to block 812 in which the user viewing device 104 attempts to authorize itself to the display device 102. To do so, the user viewing device 104 may utilize any authorization mechanism. For example, in some embodiments, the user viewing device 104 may transmit identification data to the display device 102 in block 814. As discussed above, the identification data may identify the user viewing device 104 (e.g., a serial number, GUID, or other identification data) and/or a user of the user viewing device 104 (e.g., a user number, account number, name, or other identification data).

In block 816, the user viewing device 104 determines whether the display device 102 has authorized it to view personalized image(s). If not, the method 800 advances to block 818 in some embodiments. In block 818, the user viewing device 104 may display or present a public image 420 transmitted or otherwise presented by the display device 102. For example, in some embodiments, the display device 102 may transmit a public image 420 for display (e.g., via an overlay in an augmented reality manner) to the user viewing device 104. In such embodiments, if the user viewing device 104 is not authorized, the user viewing device 104 may simply display the received public image on the local display 308. Regardless, the method 800 subsequently loops back to block 802 in which the user viewing device 104 continues monitoring for a display device 102.

If, however, the user viewing device 104 has been authorized, the method 800 advances to block 820. In block 820, the user viewing device 104 establishes the display protocol(s) with the display device 102. To do so, the user viewing device 104 may be configured to transmit a suggested, preferred, or required display protocol to the display device 102 in block 822. As discussed above, the display protocol may be embodied as a portion of the viewer protocol stored in the viewer policy database 510. Of course, rather than identifying a display protocol specifically, the user viewing device 104 may simply transmit data, on which the display device 102 may select or determine the display protocol. For example, as discussed above, the user viewing device 104 may transmit a viewer policy that includes data identifying the capabilities or features of the user viewing device 104. In block 824, the user viewing device 104 may receive the selected or identified display protocol from the display device 102. Of course, the display protocol may be embodied as features or functions inherent in the user viewing device 104 and, in such case, the user viewing device 104 may simply receive identification data in block 824 that identifies the selected display protocol. Further, in some embodiments, the user viewing device 104 and the display device 102 may not negotiate the display protocol. Rather, the display device 102 may display a personalized image 422 using a predetermined or default display protocol, and the user of the user viewing device 104 may decide whether to not to implement the display protocol on the user viewing device 104 to allow viewing of the personalized image 422. In this way, the user of the user viewing device 104 may filter which personalized images 422 are to be viewed (and the display device 102 may filter the type, content, brands, or other characteristic of the personalized images based on the display protocol used).

After the display protocol(s) has been established between the user viewing device 104 and the display device 102 in block 820, the method 800 advances to block 826 in which the user viewing device 104 facilitates the viewing of the personalized image 422 using the established display protocol. Depending on the particular display protocol used, the user viewing device 104 may display the personalized image 422 on the local display 308, project the personalized image 422 on the viewing lens 320, and/or control operation of visual features of the viewing lens 320 to allow viewing of the personalized image 422 displayed on the display 208 of the display device 102. As such, it should be appreciated that the viewable personalized image 422 may be displayed on either the display device 102 and/or the user viewing device 104 depending on the particular display protocols used. For example, in block 828, the display device 102 may display the personalized image 422 in an obscured manner on the display 208 suing a suitable display protocol (e.g., polarization, color filtering, or view segmentation), and the user viewing device 104 may control operation of the visual characteristics of the viewing lens 320 based on the established display protocol to enable a user of the user viewing device 104 to view the personalized image 422 on the display 208. Additionally or alternatively, in block 830, the display device may transmit an encrypted personalized image 422 to the user viewing device 104, which decrypts the encrypted personalized image 422 in block 830 and displays the decrypted personalized image 422 on the local display 308 or projects the decrypted personalized image 422 on the viewing lens 320 (e.g., in an augmented reality manner).

As discussed above, the display device 102 may be configured to adjust or update the display protocols based on the location of the user viewing device 104 relative to the display device 102. In such embodiments, the user viewing device 104 may display, project, or otherwise present the personalized image 422 to the user of the user viewing device 104 based on the present location of the user viewing device 104. That is, in such embodiments, the user viewing device 104 may be configured to update or adjust the display protocol consistent with the display device 102. Additionally, in some embodiments, the display device 102 and/or user viewing device 104 may update the display protocol and/or personalized image(s) based on the user's interaction with the user viewing device 104 and/or the display device 102. For example, the user of the user viewing device 104 may interact with the displayed or presented personalized image 422 on the user viewing device 104 or the display device 102 to cause the display device 102 to display or present other personalized images in response to the user's interaction (e.g., a subsequent advertisement based on the user's interaction with an initial advertisement or image). Subsequently, the method 800 loops back to block 802 in which the user viewing device 104 continues monitoring for a display device 102.

Although the system 100 has been described above in regard to the display or presentation of personalized images or video, it should be appreciated that the system 100 may be utilized to disseminate additional or other content in a private manner in other embodiments. For example, the technologies and techniques disclosed herein may be utilized to present personalized audio or other digital content using a negotiated audio protocol, similar to the video protocol described above.
